SYSTEM FORCE SENSE SWITCHES

Each channel has switches to allow connection of the force

(FOHx) and sense (MEASVHx) lines to a central PMU for

calibration purposes. There is one set of SYS_FORCE and

SYS_SENSE pins per device. For calibration purposes, it is

recommended the SYS_FORCE path be connected individually

to each PMU channel, FOH path.

TEMPERATURE SENSOR

An on board temperature sensor monitors temperatures and in

the event of the temperature exceeding a factory defined value,

(130°C) or a user programmable value, the device will protect

itself by shutting down all channels and will flag an alarm

through the latched open drain TMPALM pin. Alarm status

may be readback from the Alarm Status Register or the PMU

registers where latched and unlatched bits tell if an alarm has

occurred and whether the temperature has dropped below the

set alarm temperature.

MEASURE OUTPUT (MEASOUT)

The measured DUT voltage or current (voltage representation

of DUT current) is available on MEASOUT (0-3) with respect

to AGND. The default MEASOUT range is the forced voltage

range for voltage measure and current measure (nominally

±11.25V, depends on reference voltage and offset DAC) and

includes some over range to allow for offset correction. The

serial interface allows the user to select another MEASOUT

range of VREF to AGND, allowing for a smaller input range ADC

to be used. Each PMU channel MEASOUT line may be made

high impedance via the serial interface.

When using low supply voltages, ensure that there is sufficient

headroom and footroom for the required force voltage range.

The Offset DAC also directly offsets the MEASURE output

voltage level, but only when GAIN1 = 0.
